SpringBoot properties配置Map、List

前言

本文主要介绍properties配置Map、List的方式

一、配置application.properties文件

#list
pcp.link.attrs[0].tenantId=A
pcp.link.attrs[0].layoutId=1,2
pcp.link.attrs[1].tenantId=B
pcp.link.attrs[1].layoutId=3,4

#map
pcp.link.attrMap.A=1,2
pcp.link.attrMap.B=3,4

二、读取配置类

package com.yx.controller;

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

import java.util.HashMap;
import java.util.List;
import java.util.Map;

@ConfigurationProperties(prefix = "pcp.link")
@Component
@Data
public class LinkAttrProperties {

    //attrMap名称必须要与配置文件保持一致
    private Map<String, Object> attrMap = new HashMap<>();

    //attrs名称必须要与配置文件保持一致
    private List<LinkAttrConfiguration> attrs;

    @Data
    public static class LinkAttrConfiguration {

        private String tenantId;

        private String layoutId;
    }
}

三、使用

@Resource
private LinkAttrProperties linkAttrProperties;

@GetMapping("/test")
public void test(){

    log.info("list：{}", linkAttrProperties.getAttrs().toString());
    log.info("-----------------------------------------------------------");
    log.info("map：{}", linkAttrProperties.getAttrMap());
}
